blows from the steering wheel or other parts in case of fall, suddenlanding or the like. This combination comprises a helmet, a breastplate,thigh protectors and shin guards and each of these parts is constitutedby a central core formed by square-shaped india rubber elements one faceof which is flat and the other arched, the said elements being arrangedin separate boxes or compartments formed by vertical and horizontalstrips sewn to two inclo'sin pieces of canvas. The core thus constituteis itself confined between layers of compres ed and quilted cotton andelastic cotton with the interposition in the cotton of one or more corkplates and the whole is contained in an envelop, the outer face of whichis covered with a sheet of leather or skin in order to prevent theenvelop from being torn in contact with sharp angles.

The invention is illustrated by way of example in the accompanyingdrawing, in which:

Figure whole in 1 represents the combination as a front elevation. Fig.2 is a rear elevation thereof showing the method of attachment. Fig. 3is a front elevation of the combination to a larger scale. Fig. 1 is aside elevation partly in section. Fig. 5 is a front elevation of aportion of the partitioning receiving the india rubber elements.

' Fig. 6 is a fragmentary section showing the structure of the helmet.

The breast plate and the thigh and shin guards comprise a central coreor pneumatic cushion constituted by india rubber elements 1, which arerectangular in form in the example illustrated; these elements which areflat on one face and arched on the other, are arranged in boxes orcompart ments constituted by vertical and horizontal strips 2, sewn topieces'of canvas 3 which form the external partitions of the cushionroper. Instead of being rectangular in orm, the india rubber elements 1might be hexagonal, cubical or of any other, appropriate form. Withelements thus arranged, practlcally no vacant intervals exist when theyareplaced in their respective compartments.

On the arched side of the india rubber elements 1, a layer of elasticcotton 41 is provided, while-on the other side, a layer 5 of compressedand quilted cotton is arranged; in the middle of these layers of cottonor 1n the elastic cotton, only, a thin cork plate 6 is arranged. Thewhole is inclosed in an envelop 7 of some suitable fabric and theoutside is reinforced by a sheet of pig skin or the like 8, which servesto prevent the envelop 7 from being torn in the case of violent shockagainst an angular object.

The helmet is composed of an external portlon 8 of pig skin or the likeinside which a layer 5 of compressed and quilted cotton 1s arranged;this layer 5 is stuck to the extenor of a cork cap 6. Beneath this corkcap 6, the india rubber elements 1 are arranged between partitions, asin the other portions of the combination. Upon the other side of theelements 1, a second cork cap 6 1s arranged, so that these elements areconfined between two cork caps. The interior of the cap is thenfurnished with a linmg 9 covered with elastic cotton 4 and resting uponthe head.

The compressed and quilted cotton which enters into the composition ofall the parts of the combination and the cohesion of the elements ofpartitioned india rubber, prevent any perforation, thus preserving thewearer from fracture of the skull and the fatal effects of concussion.

The helmet is rendered integral with the breast plate by means of straps10 provided with buckles and the breast plate is connected with thethigh guards by means of straps 11 provided with buckles 12; the shinguards are connected with the thigh guards by other straps 13 providedwith buckles 14. The breast plate is held upon the aviators person bymeans of braces 15 and buckles 16 and also by a belt 17 attached to thebuckle 18. .The thigh guards are provided with buckles 19 and belts 20for fixing them to the thighs and the shin guards are furnishedcomprising a helment, a breast. thigh guards and shin guards each of Aparts being constitutedby a central of canvas, the central core beingconfined between layers of compressed and quilted cotton and elasticcotton with the interposi tion of a cork plate in the cotton, the wholebeing contained in an envelop,.the outer face of which is covered with asheet of leather or skin for preventing the said envelop from being tornin contact with sharp angled ob- 'ects.
